I have installed Magento 2.2.2.

Running php bin/magento setup:di:compile result in this error:

MagentoBackendModelViewLayoutGeneratorPool
Incompatible argument type: Required type: MagentoFrameworkViewLayoutConditionConditionFactory.php

Actual type: MagentoFrameworkAppConfigScopeConfigInterface; File: 
vendor/magento/module-backend/Model/View/Layout/GeneratorPool.php

In

vendor/magento/framework/View/Layout/Condition/ConditionFactory.php:

<?php

namespace MagentoFrameworkViewLayoutCondition;

use MagentoFrameworkObjectManagerInterface;

/**
 * Factory for composite.
 */
class ConditionFactory

 /**
 * @var ObjectManagerInterface
 */
 private $objectManager;

 /**
 * @param ObjectManagerInterface $objectManager
 */
 public function __construct(ObjectManagerInterface $objectManager)
 
 $this->objectManager = $objectManager;
 

 /**
 * @param array $elementVisibilityConditions
 *
 * @return Condition
 */
 public function create(array $elementVisibilityConditions)
 
 $conditions = [];
 foreach ($elementVisibilityConditions as $condition) 
 $conditions[] = $this->objectManager->create($condition['name']);
 
 return $this->objectManager->create(Condition::class, ['conditions' => $conditions]);
 

In

vendor/magento/module-backend/Model/View/Layout/GeneratorPool.php:

<?php
namespace MagentoBackendModelViewLayout;

use MagentoFrameworkViewLayoutScheduledStructure;
use MagentoFrameworkViewLayoutDataStructure;

/**
 * Pool of generators for structural elements
 */
class GeneratorPool extends MagentoFrameworkViewLayoutGeneratorPool

 /**
 * @var FilterAcl
 */
 protected $aclFilter;

 /**
 * @param ScheduledStructureHelper $helper
 * @param MagentoFrameworkAppConfigScopeConfigInterface $scopeConfig
 * @param MagentoFrameworkAppScopeResolverInterface $scopeResolver
 * @param PsrLogLoggerInterface $logger
 * @param FilterAcl $aclFilter
 * @param array $generators
 */
 public function __construct(
 ScheduledStructureHelper $helper,
 MagentoFrameworkAppConfigScopeConfigInterface $scopeConfig,
 MagentoFrameworkAppScopeResolverInterface $scopeResolver,
 PsrLogLoggerInterface $logger,
 FilterAcl $aclFilter,
 array $generators = null
 ) 
 $this->aclFilter = $aclFilter;
 parent::__construct(
 $helper,
 $scopeConfig,
 $scopeResolver,
 $logger,
 $generators
 );
 

 /**
 * Build structure that is based on scheduled structure
 *
 * @param ScheduledStructure $scheduledStructure
 * @param Structure $structure
 * @return $this
 */
 protected function buildStructure(ScheduledStructure $scheduledStructure, Structure $structure)
 
 parent::buildStructure($scheduledStructure, $structure);
 $this->aclFilter->filterAclElements($scheduledStructure, $structure);
 return $this;
 

What is the fix?

It used to be there but was removed. Make sure no di.xml still references it. So look for something like this:

<preference for="MagentoFrameworkViewLayoutGeneratorPool"
 type="MagentoBackendModelViewLayoutGeneratorPool" />

On the cause:
It looks like you copied Magento 2.2 over an earlier version and something botched your upgrade path. Did you follow these instructions?

https://github.com/magento/magento2/tree/2.2/app/code/Magento/Backend/Model/View/Layout

You can see there is no GeneratorPool.php file there

Be sure you are working with stable version, you can download from here https://magento.com/tech-resources/download

I removed

vendor/magento/module-backend/Model/View/Layout/GeneratorPool.php

entirely which then allowed the compile command to process normally.

Got the suggestion from https://github.com/magento/magento2/issues/11190
